PROTECTIVE SLEEVE

BA C K G R OUND O F T H E I NV E NT I ON

Field of the Invention

The present invention relates to a protective device for use in protecting various parts of the human body during physical activity, in particular during sporting activities, and more particularly pertains to a tubular, minimally compressive sleeve having at least one integrally formed impact absorbing portion. The impact-absorbing portion provides for effective dissipation of impact forces and thereby protects the body part underlying the sleeve from injury.

Description of the Prior Art

The general problem of providing protection from injury to various parts of the human body has been addressed in the prior art. In particular, various means and apparatus have been developed for protecting or guarding the shin, the ankle, the elbow, the knee, and other body parts. These apparatus find particular application in the field of sports where physical contact is a necessary outcome of participation in the sport. Padding and guards are employed to both minimize painful impacts and decrease the number of injuries such as bone splinters and fractures. One such guard is disclosed in U.S. Patent No. 2,785,407 to Reeder which shows a thigh protective pad. Pads of the type disclosed in Reeder are intended to be worn underneath various items of clothing including socks, shirts, and pants and as such are generally free to shift position while in use.

Pads and guards find particular application in protecting the tibia, and in particular the anterior shin portion thereof, of soccer players. The most common injury to a soccer player is caused by other players attempting to kick the soccer ball and instead kicking the shin of another player. Guards positioned anteriorly of the shin serve to dissipate the impact of such kicks Shin guards are commercially available as semi-rigid members which are worn under the sock of a player. These guards are generally not comfortable to wear as the material is not soft and abrades the skin of the leg. Furthermore, guards of this type have a tendency to slide down the leg to a position wherein the mobility of the ankle is limited.

A shin guard of a modified design is disclosed in U.S. Patent No. 4,306,315 to Castiglia. The device includes an elastic tubular member adapted to tightly surround the lower leg of a wearer in the vicinity of the shin. A substantially rigid member is tapered toward the lower end thereof and is adapted to be received in a retaining means in such manner that the rigid member is positioned between the elastic tubular member and the shin of the wearer. This device suffers from the disadvantage of holding onto the leg by compressing the lower leg of the wearer and thereby producing a tourniquet effect and restricting the flow of blood therethrough.

A device for protecting both the shin and ankle of a user is disclosed in U.S. Patent No. 5,507,720 to Lampropoulos . The protector includes a shin protecting portion and an ankle protecting portion which may be flexibly connected one to the other. The shin protecting portion and ankle protecting portion are attached to the leg and ankle respectively by means of straps. The leg strap necessarily compresses the leg in order to hold the shin protecting portion in position. It would therefore be desirable to provide a guard for use in protecting various body parts from injury that adheres to the portion of the body to be protected in such manner that a tourniquet effect is avoided. It would further be desirable to provide such a guard having at least one integrally formed impact absorbing portion in a tubular sleeve and thereby obviating the need for positioning pads under items of clothing and/or affixing a plurality of pads to body parts located proximal to one another.

SUMMARY OF THE INVENTION

Accordingly, it is a primary object of the present invention to provide a tubular, non-compressive sleeve having at least one integrally formed impact -absorbing portion for protecting a body part disposed in underlying relationship to the at least one impact -absorbing portion.

With reference now to the drawings, and in particular to Figures 1 through 7 thereof, a first preferred embodiment of the protective sleeve embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the sleeve 10 is shown in Figure 1 and includes a body 11 which is preferably formed of resiliently stretchable non-compressive material such as urethane or polyurethane . The body 11 is sized and configured to snugly conform to the lower leg of a wearer. The urethane material is advantageously soft at body temperature and naturally adheres to the wearer's skin with negligible compression, thereby preventing blood flow restriction and the shifting or sliding down of the sleeve 10 upon the wearer's leg during physical activity.

A tapered impact -absorbing portion 12 is formed substantially along a longitudinal extent of the body 11 and spans approximately 1/3 of its circumference in order to protect the shin from side impacts as well as frontal impacts. The tapered impact-absorbing portion 12 includes top portion 16 disposed proximate a first reinforced end portion 14 and a bottom portion 17 disposed proximate a second reinforced end portion 20, the top portion 16 being of greater lateral extent than the bottom portion 17 to generally follow the profile of the lower leg. The impact -absorbing portion 12 is integrally formed by building up the material of the body 11 along an anterior portion 13 thereof as shown in Figure 3. The resulting configuration provides for an anterior portion 13 of greater thickness than a posterior portion 15.

The first reinforced end portion 14 preferably includes an integral fabric weave which provides for circumferential stretchability or elasticity. Alternatively, the material composition may be such that the same stretchability is effected. The circumferential stretchability allows for elasticity about the upper portion of the lower leg so as not restrict blood flow. The fabric weave additionally provides for added strength at the first end portion 14 and prevents tearing of the sleeve 10. The integral weave does not increase the compression about the lower leg.

The second reinforced end portion 20 is shown disposed opposite the first reinforced end portion 14 and is of smaller diameter than the first reinforced end portion 14. The second reinforced end portion 20 preferably includes an integral weave which provides for limited circumferential stretchability or elasticity and which additionally prevents tearing of the sleeve 10. Alternatively, the material composition may be such that the same stretchability is effected. The integral weave does not increase the compression of the urethane material. The second reinforced end portion 20 is sized to generally conform to the lower portion of the lower leg. With reference to Figures 2 and 4, an alternative embodiment generally designated at 30 of the first preferred embodiment is shown including a tapered pocket 32 formed in the impact-absorbing portion 12. The pocket 32 is preferably formed in such manner that an opening 33 is formed proximate the first reinforced end portion 14. A tapered insert 34 formed of impact resistant nylon, high density urethane or other rigid or semi-rigid material is insertable into the pocket 32 to provide additional impact resistance if desired. In use the sleeve 10 or 30 is positioned over the lower leg of the wearer in such manner that the impact absorbing portion 12 overlays the tibia 35 as shown in Figures 3 and 4. The fibula 36 is also protected by the sleeve of the present invention. The first and second reinforced end portions 14 and 20 provide added mechanical strength and prevent tearing when the sleeve 10 is being positioned past the foot and ankle.

With reference to Figure 5, a second alternative embodiment of the present invention is shown including a sleeve generally designated 40. The sleeve 40 is of generally truncated conical configuration conforming generally to the shape of the lower leg. The sleeve 40 includes a first impact -absorbing portion 41 formed as previously described along a longitudinal extent thereof for the protection of the shin. A pair of ankle impact-absorbing portions 42 are formed at a bottom end 43 of the sleeve 40 and extend beyond the bottom end 43 in generally semi-ellipsoidal fashion to overlay the medial and lateral ankle bones of the wearer. A pair of knee impact-absorbing portions 46 are formed at a top end 45 of the sleeve 40 and extend beyond the top end 45 in generally semi-ellipsoidal fashion to overlay the medial and lateral portions of the knee. The ankle and knee impact-absorbing portions 42 and 46 are formed in a manner similar to the first impact -absorbing portion 41.

With continued reference to Figure 5, the sleeve 40 is shown including a first reinforced end portion 47 and a second reinforced end portion 48 of similar construction and composition as the first and second reinforced end portions 14 and 20. As shown, the first and second reinforced end portions 47 and 48 include the ankle impact-absorbing portions 42 and the knee impact -absorbing portion 46.

A third alternative embodiment is shown in Figure 6 and includes a sleeve generally designated 50 of generally truncated conical shape conforming generally to the shape of the lower leg and knee. The sleeve 50 includes an upper portion 51 which in use extends above the knee of the wearer. A first impact -absorbing portion 52 is formed along a longitudinal extend of the sleeve 50 for overlaying protection of the shin and knee. The first impact-absorbing portion 52 further includes a knee protection portion 53 formed at an upper end 54 thereof. The knee protection portion 53 includes a plurality of knee flexion grooves 55 formed transversely of the longitudinal axis of the sleeve 50. The knee flexion grooves 55 allow for flexion of the knee during use while maintaining the knee protection portion 53 in overlaying relationship to the knee.

First and second reinforced end portions 55 and 56 are of similar construction and composition as the first and second reinforced end portions 14 and 20.

A pair of ankle impact-absorbing portions 57 are formed at a bottom end 58 of the sleeve 50 and extend beyond the bottom end 58 in semi -ellipsoidal fashion to overlay the medial and lateral ankle bones of the wearer. As shown, the second reinforced end portion 56 includes the ankle impact - absorbing portion 57.

A fourth alternative embodiment is shown in Figure 7 and includes a sleeve generally designated 60 having a generally truncated conical configuration conforming generally to the shape of an arm. The sleeve 60 includes a reinforced wrist end portion 61 and a reinforced shoulder end portion 62. The sleeve 60 further includes a shoulder portion 63 formed at one end thereof having an impact absorbing portion 64 formed along a longitudinal axis of the sleeve 60. The impact-absorbing portion 64 includes a plurality of shoulder flexion grooves formed transversely therethrough for flexion of the shoulder during use while maintaining the shoulder protection portion 63 in overlaying relationship to the shoulder. A lower arm impact-absorbing portion 65 is formed at an opposite end of the sleeve 60 and extends from the reinforced wrist end portion 61 to a position whereby the elbow of a wearer is protectively covered thereby. An elbow portion 66 of the lower arm impact -absorbing portion 65 formed at an end thereof distally of the wrist end portion 61 includes a plurality of elbow flexion grooves 68 formed transversely therethrough for flexion of the elbow during use while maintaining the elbow protection portion 66 in overlaying relationship to the elbow. First and second reinforced end portions 69 and 70 are of similar construction and composition as the first and second reinforced end portions 14 and 20. To conform to the shape of the arm, the first reinforced end portion 69 is of smaller diameter than the second reinforced end portion 70.

A strap 71 is shown integrally formed to the sleeve 60 and extending from the shoulder portion 63 from a position adjacent the impact-absorbing portion 64. The strap 71 is adapted to attach to a pair of pants or the like in a conventional manner to help in preventing the sleeve 60 from shifting upon the arm of a wearer.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

STATEMENT UNDER ARTICLE 19 (1)

This amendment is submitted in order to clarify and more clearly distmguish the sub_ject matter of the claims from the references indicated as relevant in the Search Report of 6 September 2000.

The Palmer et al. reference 5,983,391 discloses a protecnvc sleeve adapted for a body member compnsing a tubular body member having a tapered impact absorbing portion formed along an anterior portion of the sleeve and extending along a longitudinal extent with first and second reinforced opposed end portions. The base claim. Claim 1, has been amended so as to render it more clearly free of the cited reference, with each of the dependent claims now including the limitations of the independent claim. Specifically, Claim 1 now recites a tubular sleeve having an impact portion formed along an anteπor portion and extending along a longitudinal extent in combination with the upper end of the sleeve having a pair of knee impact portions compnsing a plurality of transverse grooves being formed therethrough, with a pair of opposed ankle impact absorbing portions formed proximate to the second end portion. This combination of features is not apparent from a review of the disclosure of Palmer, since it neither suggests nor provides this facility.

The Bodenschatz ct al. reference 5,419,161 discloses a protecnvc sleeve adapted for a body member compnsing a tubular body member having an impact absorbing portion formed along an anteπor portion of the sleeve and extending along a longitudinal extent with first and second reinforced opposed end portions. As discussed above, the base claim. Claim 1, has been amended to recite a combination of features which is not suggested in Bodenschatz, thereby rendering the claim free of the cited reference.

Lerman 4,832,010 recites a protective sleeve compnsing an impact absorbing mateπal made from a polyurethane mateπal The independent claim 1 has been amended, with the dependent claims 5-7 including the limitations of claim 1. Therefore, these dependent claims are now considered to be presented in allowable form.

This amendment is submitted in order to expedite the full consideration of this case. An early and favorable response is hereby earnestly solicited.
